    Ensure that haproxy spawned by the metadata agents is active

    In both neutron-metadata and neutron-ovn-metadata agents we should
    ensure that haproxy service spawned for network/router is actually
    active before moving on.
    This patch adds that check and this is similar to what was already
    implemented some time ago for the dnsmasq process spawned by the dhcp
    agent.
